There was probably a bad solder connection at the J7 lug, or the trace may have been broken there.
So originally, there should have been a short (equivalent of a piece of wire) between the blue wire and pin7. The short went open (no connection) and started arcing. You bypassed the open by providing a new short and making a direct connection from the blue to pin7.
Hope that makes some bit of sense.
